The Sun Hydraulics RSJS8WV (RSJS8WV) is a normally closed poppet valve element featuring an integral pilot control cavity, designed for precise pressure regulation in hydraulic systems. This valve is externally drained and utilizes a balanced poppet design, making it suitable for applications requiring stable pressure control despite variations in back pressure at port 2. The RSJS8WV can replace two-port relief valves when there is pressure in the return line, offering versatility in various hydraulic circuits. It operates by opening the poppet element to port 2 when the inlet port 1's pressure reaches the pilot control cartridge's setting, thereby throttling flow to regulate system pressure. The pilot control cavity accommodates any T8A pressure control cartridge, which must be installed separately and adjusted to its specific torque value for optimal performance. The valve's main stage orifice is protected by a 150-micron stainless steel screen, ensuring durability and reliability under high-pressure conditions up to 5000 psi (350 bar). Its design incorporates Sun's floating style construction, minimizing internal binding risks due to installation or machining variations. Additionally, the RSJS8WV supports cross-port relief circuits and can handle maximum pressures at port 2. With a capacity of 120 gpm (480 L/min), this sequence valve offers quick response times of approximately 2 milliseconds and maintains minimal leakage at reseat with only about 10 drops per minute. It requires specific installation torques for both the main stage (350-375 lbf ft) and pilot control valves (20-25 lbf ft). The RSJS8WV weighs approximately 3.10 lb (1.40 kg) and comes equipped with Viton seals for enhanced performance in demanding environments.

This valve is a normally closed poppet element that incorporates an integral pilot control cavity. It is externally drained, and is a balanced poppet design. The pilot control cavity will accept any T-8A pressure control cartridge. When the pressure at the inlet (port 1) reaches the pilot control cartridge's setting, the poppet element starts to open to port 2, throttling flow to regulate the pressure. The pilot cartridge's setting determines the difference in pressure between the inlet (port 1) and the drain (port 3). These valves are insensitive to back pressure at port 2, up to the valve setting. They may be used to regulate pressure in place of 2-port relief valves if there is pressure in the return line.
- All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
- Pilot flow continues to increase as the pressure at port 1 (inlet), relative to the pressure at port 3 (drain), rises above the valve setting.
- The main stage orifice is protected by a 150 micron stainless steel screen.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
- NOTE: With the -8 control option, the main stage valve should first be installed to the correct torque value. The T-8A pilot control valve should then be installed into the main stage valve to its required torque value.
- The -8 control option allows the pilot control valve to be incorporated directly into the end of the relief cartridge via the T-8A cavity. These pilot control cartridges are sold separately and include solenoid operation, air pilot operation, and hydraulic pilot operation. See Pilot Control Cartridges.
- Because the modulating occurs inside the cartridge these valves are immune to most of the problems associated with cavitation, namely noise and manifold erosion.
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
